Detailed Description

Member Function Documentation

If we completed all io we sent during current sample... we can't have any problem...and we can't measure io throughput, so don't add measurement

We did have lag last second... increase m_lag_cnt and check if it has reached maxlag_cnt

We did not have lag...reset m_lag_cnt

And finally rotate sliding window
